This invention relates to :i pipe fitting for use with pipes having :in enamel or vitreous` coating, the fitting boing pmticulaly iiflzipteil for use for the support of railings und fstuneliiozis, suoli is are used in subway and elevated trains, publie buildings, :mel analogous places frequente@ by the publie, although it will be readily appreciated thai' the fittings muy lie need in numerous Ways und fo1'-\.':1iie l purposesn v Une of the principal objections against ille employment of eiizmiel pipes for use :is reste o1' supporte which muy lie giiipped by l'iiiseengers, has been that, owing ao the extreme. lii'itlenese oiE ille vil/remis oi' enei'riel coating, the ends of lie pipe which engage the couplings or* i'ittioge invariably*become chipped, due to eoutnel'. lieiween vle enamel coating uml the sides; of the izting.

provided the restricted 31 '-ef'leii glso'ioe is?,

the diameter of Wliioli if oi 'will l, le than and. .is mile-pied to engage me time me' @ivow tremity of the pipe 5. The cylindrical body 7 therefore acts as a guard and completely incloses the end of the pipe 5, so that such checks and scars as may be caused by the contact of the threads and the slight distortion ofthe pipe end as it is forcibly screwed into the floor or ceiling flange, are incased and hidden.

The T-coupling disclosed in Fig. 2 comprises a cylindrical body 1l, similar to the cylindrical body 7 of the floor or ceiling flange previously described, the cylindrical body in this instance forming the leg of the T-coupling, the head l) of which may be similarly formed if so desired, but is preferably constructed so asv to receive a pipe completely theretln'ough, so that the continuity thereof may be preserved. The head 12 of the T is provided with the spaced and contracted internal ledges 13, the same being located upon opposite sides of the opening communicating with the cylindrical body 11 and are spaced a distance from the free and opposite extremities of the head, and are of such size as to nicely receive the pipe 14 therein, which is provided with the enamel coating 15.

The leg 11 of the T is provided with a restricted and running thread 17, allowing the pipe 5 to act as a set screw and forcibly engage the continuous pipe 1l, to thereby lock the coupling in place upon the pipe 14 and hold the right-angle pipe in position. This manner of securing the coupling and rightangle pipe to the pipe 1l, allows for the preservation of the continuity of the latter, so that the post or stanchion 5 is of one piece, a desirable feature. Theset screw action of the pipe 5 causes the ledges of the T to forcibly engage the continuous pipe with the result that the fragile coating thereof adjacent these ledges becomes cracked and broken, but, owingr to the fact that these ledges are spaced a considerable distance from the ends of the head ofthe T, the checks and jagged edges so formed are completely inclosed and hidden'.

W'hat we claim is t'k 1. The combination of a pipe having a vitreous coating and a fitting therefor comprising a hollow cylindrical member with the internal diameter thereof relatively greater than the external diameter of the said vitreous coating` and provided with a threaded portion spaced a distance from the extremity of said cylindrical member and of relatively less diameter than the same, the said pipe, with the vitreous coating, extending within said cylindrical member, spaced from the side walls and engaging the threaded portion thereofA and a threaded extremity,`

. 3. The combination of a V second-mentioned 2. The'combination of a pipe having a vitreous coating, and a fitting therefor comprising a hollow cylindrical member with the internal diameter thereof relatively greater than the external diameter of said vitreous coating and provided with a reduced portion spaced a distance from the extremity of said cylindrical member and ofi relatively less diameter than the same, the said pipe with the vitreous coating extendingA within said cylindrical member, spaced from the side walls and engaging the reduced portion thereof.

pipe having a vitreous coating, and a fitting therefor comprising a hollow cylindrical member with the internal diameter thereof relatively greater than the external diameter of said vitreous coating and provided with a reduced portion spaced a distance from the free extremity of said cylindrical member and of relatively less diameter than the same, the said pipe with the vitreous coating extending within said cylindrical member, spaced from the side walls and engaging the reduced portion thereof, a head carried by said hollow cylindrical member, and a second pipe with a vitreous coating thereon extending through said head and held fixed with relation thereto by the first-mentioned pipe.

4. The combination of a pipe having a vitreous coating, and a fitting therefor comprising a hollow cylindrical member with the internal diameter thereof relatively greater than the external diameter of said vitreous coating and provided' with a reduced portion spaced a distance from the free extremity of said cylindrical member and of relatively less diameter than the same, the said pipe with the vitreous coating extending within said cylindrical member, spaced from the side walls and engaging the reduced portion thereof, a sleevelike head carried by said hollow cylindrical member and provided with internally contracted ledges spaced a distance from the free extremities of said sleeve, and a second pipe with a vitreous coating -extending through said sleeve-like head, contacting with said internally threaded ledges and receiving the first-mentioned pipe thereagainst, holding said first-mentioned pipe, pipe and fitting, in fixed position.
